The LED that you have has to be mounted on a heatsink of about 100x100 mm.Dear Vbase,
Sorry I did not mention its voltage its 12V 20W.
But 20W is not actual power, its light intensity is equal to 20W Light. but actual power is low.
There is no such thing as 20W of light. Light intensity is measured in the amount of Lumens. An old 100W incandescent light bulb produces less intensity as a 20W LED. 20W is the amount of heat it produces when it has its rated current.But 20W is not actual power, its light intensity is equal to 20W Light. but actual power is low.
